[For 1.8] Square theme

[grateful_dead]

Hi eNvy, thanks for nice theme i've installed.
However,when i try to reach my forum with a different screen resolution, i can't click dropdown menu which is
<i class="fa fa-angle-down fa-lg"></i>

Which resolution? The theme is fixed to 1024px.

i change the resolution but it doesnt change. Also i have visited other forums which installs Square, jquery login box and dropdown works. Does problem stem from plugins?
